That’s pants and not a practical solution for me. I’d be shocked if they are not working on a fix for it. Unless they see it as an opportunity to force new hardware purchases which would be pretty low.
Same issue my side. On the same wallbox firmware version (5.17.87) and can’t get the handshake between Macan and Wallbox Pulsar Plus (22kw) so that scheduled charging operates with Octopus Inteligent Go tariff. Annoying! Has worked fine on all my other EVs. Have raised it with Wallbox support...
